Ok I will bite. So if a man or lady decides to sell the body they own, do it in safe way and earn a living doing so is wrong in your opinion. I see it different as most libertarians do. The effort of ones labour is their property, and worth, if they can earn a living doing why should a government interfere with ones personal effort. If that effort is selling your body, it is your choice, as it would be my choice to engage a the services of a prostitute. That is called free will and making a personal choice. One could also argue, that by not making it legal, then it forces those who sell own body to do it in dark. While in the dark, it creates the easy access for the criminal element to move in and take over, because it is not legal. The same reasoning can be made for drug use, illegal firearms, all those reason allow the criminal market to exist.
So if you reason it out that way, in my opinion, the government is creating the conditions for criminals/criminal element to exist.
Further, marijuana and the current policy of the feds and Prov will not remove the criminal elements from the market, it will only allow it to further increase. If MJ was treated with same rules as basil plant you buy in the store, it would disappear from the criminal market as everyone would be free to grow, smoke, start a business and sell the product (free market). As it stands now, all the free market entrepreneurs are being raided and closed down. This is to ensure the government approved growers, suppliers and markets are controlled and taxed. If people can understand the basics of free markets verses government controlled and regulated markets..then the business industry would flourish in Canada.
Another example: NAFTA = Free Trade - Nothing could be further from the truth in Free Trade. NAFTA is government designed, big business designed tool to ensure only those who join the club and have lobby group can play in the NAFTA field. All others have been shut out, due to the governments control and access to those markets. So NAFTA is free trade, it another form of control for big business to maintain market share and stifle any new competition.
If you can understand how the government controls all of your choices from Healthcare, Taxation, Schooling, business and markets, then you might get mad enough realize you are tool, and slave to power and control of the government over you personal life.
Read this book. "Tea Party of One", By Jean-Serge Brission. A business owner who since 1991 has refused to collect PST/GST and is still in business (Greely, Ontario) and does not collect taxes on behalf of the government. His SC argument is tax collection without proper compensation for the value of his work and to be fairly compensated for his time and effort is slavery. A challenge that no level of government is willing to take to court, because the outcome will have far reaching effects on the Canadian tax system. So they leave him alone and let him do his thing...an Army of one is ignored...but he is legally right.
